How do you think points, lines, and planes are related to Geometry?
Why do you think it's important to have shared conventions around these things?
Let's talk about POINTS ...
Looks like ...
Named as ... "Point A"
Facts ...
They have no shape or size
Collinear: Points on the same line
Noncollinear: Points not on the same line
Let's talk about LINES ...
Looks like ...
Named as ... "Line AB" or "Line G"
Facts ...
Made up of points, no thickness
There is only one line through any two points
Lines intersect at one point
Let's talk about PLANES ...
Looks like ...
Named as ... "Plane ABC" or "Plane P"
Facts ...
Extends indefinitely in all directions
Created by 3 noncollinear points
Coplanar: points on the same plane
Intersect at a line
